The busbar for holding a contact wire of electrically driven vehicles has an elongate, integral box profile which is slotted in the longitudinal direction and has two mutually opposite spring-elastic tensioning arms and spring-elastic clamping arms fitted at the ends of the tensioning arms. In order to prevent corrosion as the result of condensation water, bores (26, 27) are introduced into the clamping arms (7, 8) and are close to tips (9, 10) of the clamping arms, which tips are held by a contact wire (2). Preferably, these bores (26, 27) are fitted in pairs and have a distance of one third of the total length of the busbar from the respective end of the busbar.
